If the FedEx integration is a third party module you should contact the developer for support. They will likely ask for login details for your hosting account so they can check the situation.
This is not the kind of question that can easily be answered via a forum like StackExchange. Every Magento installation is different and there is no instant fix for an issue like this.
An alternative would be to get in contact with a certified Magento developer in your area:

I think you should enable some shipping methods: http://www.magentocommerce.com/knowledge-base/entry/shipping-carriers-setting-up-fedex (take a look at the Allowed Methods list secion). Also the error is about wrong address.
